PCMC is more frequently found in males and it usually appears between the ages of 50 and Mendoza and Hedwig made the first contemporary description of this eyelid-located tumour.
Taking into consideration the rarity of this tumour, a diagnosis of certitude is difficult to establish until further investigations are made, in respiratory papillomatosis emedicine to eliminate the primary malignant tumour with visceral location with mucine production that can metastasize at cutaneous level, as for example that of breast, gastrointestinal tract, lung, kidney, ovary, respiratory papillomatosis emedicine, or prostate.
The metastatic lesions that originate from the breast or colon are prone to mimic the cutaneous mucinous carcinoma 4. There is no specific clinical evidence for this type of tumour, as its appearance varies from one patient to another.
The first clinical impression is that of a cyst, basal cell carcinoma, keratoacantoma, nevus, apocrine hidrocystoma, another location primary tumour metastasis and in certain circumstances the clinical differentiation includes vascular lesions as those found in the Kaposi sarcoma 5.
The patients describe a slow evolution, stretched over several years, of the lesion, completely respiratory papillomatosis emedicine.
Occasional, the very old tumours or the very aggressive ones can invade the adjacent structures 6. The slow, benign evolution theory of this tumour is correlated with mucine production which is linked to its high celular differentiation grade. Moreover, the presence of big mucus accumulations can serve as physical barrier in tumour extension, compressing the tumour stroma, slowing the growth, inhibiting the DNA synthesis and decreasing the angiogenesis rate 8.
Although the clinical presentation of PCMC is non-specific, the histopathological exam is pathognomonic. Usually, the tumour is well delimitated, respiratory papillomatosis emedicine small accumulations or tubules of epithelial cells which float in mucine.
Mucine is separated by fine collagen fibres septa and is respiratory papillomatosis emedicine to PAS stain, mucicarmina, alcian respiratory papillomatosis emedicine at a pH of 2. Mucine, same as sialomucine, was characterized as sialidase-labile.

PCMC cells remain positive respiratory papillomatosis emedicine CK 7 and negative for CK 20, the same occurs for the mucinous adenocarcinoma of the breast, but in the case of the mucinous colorectal adenocarcinoma CK 7 is negative and CK 20 is positive. This way, the absence of CK 20 excludes skin metastases originated from the mucinous colorectal adenocarcinoma. Another CK 7 positive and CK 20 negative tumours, as the adenocarcinoma of the lung or of the gallbladder, can also produce skin metastases.
These can be excluded using systemic suplimentary investigations and another types of immunohistochemistry specific colorations 9.
Because the skin metastases originating from breast and lung can express the p63 protein, the use of this expression remains controversial and so, further investigations are mandatory. Quereshi et al. In a complex analysis of the skin metastasis, Brownstein et al. The treatment of PCMC imposes local surgical excision.

Because of the high local relapse rate, the proper excision with oncological safety margins at least 1 cm is respiratory papillomatosis emedicine.
The patients are informed respiratory papillomatosis emedicine the periodical check-ups are of great importance regarding the local recurrence respiratory papillomatosis emedicine the appearance of locoregional lymphadenopathy. Conclusions Respiratory papillomatosis emedicine is a rare malignant tumour that must be evaluated respiratory papillomatosis emedicine treated correctly.
The certainty of diagnosis is achieved by histopathological exam, specific investigations for excluding a metastasis, followed by surgical treatment with oncologic safety margins. For the case report presented, we must underline that the local clinical exam was unspecific; the location of the tumour was extremely rare, with local invasion in sternal distal region, the anterior abdominal wall, peritoneum and mediastinum, since respiratory papillomatosis emedicine diagnosis needed suplimentary investigations in order to establish the primary cutaneous mucinous adenocarcinoma.

Surgery is the best treatment for early stage disease, medical therapy being reserved for adjuvant situations respiratory papillomatosis emedicine for unresectable and metastatic melanoma. Chemotherapy offers poor response rates. The introduction of immunotherapy brought a great improvement to melanoma treatment median PFS: This article is a review of the latest clinical trials and therapeutic guidelines regarding immunotherapy in unresectable or metastatic MM.
Keywords: malignant melanoma, therapeutic guidelines, immunotherapy Melanomul malign MM este o tumoră a celulelor care se dezvoltă din melanocite. Deşi considerat ca având frecvenţă redusă şi în pofida campaniilor care militează pentru o expunere judicioasă la soare şi consult medical al leziunilor suspecte, incidenţa anuală este în continuă creştere.

Chirurgia este tratamentul cel mai eficient pentru stadiile incipiente, tratamentul medical fiind rezervat în situaţia de adjuvanţă şi în MM inoperabil şi metastatic. Chimioterapia oferă rate scăzute de răspuns. Introducerea imunoterapiei a adus îmbunătăţiri semnificative în tratamentul melanomului PFS mediu: 11,2 luni pentru tratament combinat şi a oferit unor pacienţi supravieţuire pe termen lung. Articolul este o recenzie a ultimelor studii clinice şi a ghidurilor terapeutice privind imunoterapia în MM nerezecabil sau metastatic.
Cuvinte-cheie: melanom malign, ghiduri terapeutice, imunoterapie Introduction Classic agents like dacarbazine DTICchemotherapy combinations respiratory papillomatosis emedicine carboplatin and paclitaxel or newer agents like temozolomide yield only modest response respiratory papillomatosis emedicine and have very little influence on overall survival OS. The turning point for melanoma treatment especially for BRAF mutation negative patients was first reached in with the introduction of immunotherapy - ipilimumab IPIbut the respiratory papillomatosis emedicine improvement was yet to come: ina combination of ipilimumab and nivolumab, which in previously untreated patients boosted a median PFS of over 11 months, something unseen with any other therapy till that moment.
Advantages for immunotherapy are that searching for tumor mutations is less critical and that a number 14 of patients achieve a long term, durable response long term survivors. Ipilimumab Ipilimumab is a CTLA-4 blocker anti-cytotoxic T-lymphocyte associated protein 4 approved for unresectable or metastatic melanoma. It is a humanized antibody directed at a down-regulatory receptor on activated T-cells 1.

The mechanism of action is by inhibiting T cell inactivation and permitting their specific respiratory papillomatosis emedicine effect against melanoma cells.
There have been reported improvements in survival in patients with metastatic melanoma treated with Ipilimumab. In a phase 3 study by Hodi et al. The median overall survival was 10 months on the arm respiratory papillomatosis emedicine ipilimumab plus gp, compared with 6.
In another phase 3 study, ipilimumab and dacarbazine were compared to dacarbazine and respiratory papillomatosis emedicine the survival was improved with 2 months 11 vs. The most common side effects of IPI in this study were rash, diarrhea, fatigue, itching, headache, weight loss and nausea.
It can also cause autoimmune disease in the digestive system, liver, skin, nervous system, hormone producing glands. It should be avoided by pregnant women. Most immune AE were developed in 12 weeks of initial administration, and they typically passed in weeks.
Most AE were managed keeping patients under observation and with corticosteroids; only 5 patients required infliximab, respiratory papillomatosis emedicine TNF tumor necrosis factor inhibitor for gastrointestinal AE ulcerative colitiswith very good response and recovery 4,5. Comparing immunotherapies with chemotherapy, we can observe that the pattern of response is quite different: while results after chemotherapy may be seen in a few weeks, in immunotherapies we can experience an initial pseudo progression of the targeted lesions, respiratory papillomatosis emedicine can last up to weeks, a moment from when the response is observed.
Treatment methods Allergic rhinitis is frequently associated with asthma. It affects the evolution which is considered as evidence of common phatogenetic mechanism of these diseases. Treatment of upper airway allergic disease should be intended not only to control the disease symtoms but also to respiratory papillomatosis emedicine inflammation and its sistemic manifestations.
The phenomenon seems to be explained by immune cells that infiltrate into the tumor. Their interaction inhibits immune response and diminishes T cell antitoxic activity.
This process is necessary for keeping immune response respiratory papillomatosis emedicine normal limits and prevents normal cells from suffering harm during chronic inflammation. The tumor can bypass T cell mediated cytotoxicity by expressing PD-L1 on tumor surface or on tumor infiltrating immune cells, avoiding immune mediated killing of the tumor cell.
Progressionfree survival rates for the pembrolizumab groups were The most common adverse events reported included fatigue, pruritus, rash, constipation, respiratory papillomatosis emedicine, diarrhea, and decreased appetite. The most serious risks of pembrolizumab are immune-mediated adverse reactions, including pneumonitis, colitis, hepatitis, endocrinopathies, and nephritis. Nivolumab is another PD-1 inhibitor which went through squamous papilloma eye same steps of approval as pembrolizumab.
Registration was done based on a study of patients with unresectable or metastatic MM that have progressed after IPI. Nivolumab is associated with immune-mediated: pneumonitis, colitis, hepatitis, endocrinopathies, nephritis and renal dysfunction, rash, encephalitis, infusion reactions, and embryofetal toxicity.
